Definitions
- the invention relates to a blood sampling device a tube in which a separating body is arranged, its specific weight between the specific Weights of the blood components to be separated.
- Such blood collection devices are known from DE 27 11 336 C2, DE 27 34 720 or EP 0 056 609. If these blood collection devices are a tube made of relative Use soft plastic that is used when centrifuging under the force of the liquid contained in it is expanded and around the separator a gap is the softness of the tube often disadvantageous. On the one hand, a soft tube to be able to use and on the other hand the blood collection device resistant to external influences To do is in EP 0 305 459 B1, of which the preamble of claim 1, a blood collection device described, which is a relatively rigid outer tube and a relatively soft one contained therein Has inner tube, which during centrifugation can expand.
- a separator with a breakable piston rod is provided between the outer tube and the inner tube and thus at the same time as a piston for drawing a blood sample into the blood collection device can be used.
- the cannula hub of the outer tube can cause the blood to flow back preventing valve may be provided or one of the Cannula to be pierced. If the cannula hub contains a membrane to be pierced by the cannula, when centrifuging there is a risk that the force of the liquid column contained in the inner tube Liquid escapes along the membrane.
- the invention has for its object a blood sampling device to create where the danger of unintentional liquid leakage in the centrifuge is eliminated.
- a centrifuge insert is provided the one shot for the one pierceable Has membrane-containing cannula attachment, the Recording a pin arranged to support the membrane is. This will make the cannula hub with the membrane at the puncture site during centrifugation reinforced sealed. At the same time, the centrifuge insert supports the outer tube and prevents the cannula hub axial due to the centrifugal force is squeezed.
- the centrifuge insert can be used as separate part can be inserted into the centrifuge cup, however, it can also be firmly contained in the centrifuge cup be.
- the 1 has a cylindrical one Outer tube 10 from a relatively rigid, clear plastic on which one also transparent, cylindrical inner tube 11 from one Material that is softer than that of the Outer tube 10.
- the inner tube 11 extends almost over the entire length of the outer tube 10.
- the outer tube 10 has one at its front end End wall 13 on the tube wall of the tube in one piece is integrally formed and of which a centrally arranged Cannula cone 14 protrudes. Through the cannula cone 14 extends an axial channel 15. On the Cannula cone 14 is a hand-removable, attached Cap 16, which forms the cannula attachment 17. This cap 16 contains a channel 15 which closes elastomeric membrane 18 that can be pierced.
- the ring 19 serves as a retaining ring for a multiple sampling cannula 21.
- the multiple sampling cannula 21 has a tubular, plastic Handle 22 on the axially displaceable and rotatable on the essentially cylindrical cannula hub 17 sits.
- the handle 22 is with holding cams 23 provided between the ribs 20 of the ring 19th grab and by turning the handle 22 with the Ribs 20 are locked.
- a hub 24 At the front of the Handle 22 is a hub 24, the one cannula 26 sharpened on both sides, the rear shorter part 25 protrudes into the handle 22.
- the front part of the cannula protrudes outwards serves to puncture the vein.
- the shorter cannula part 25 is surrounded by a rubber hose 27. If the handle 22 is attached to the cannula attachment 17, the rear cannula part penetrates the protective tube 27 and the membrane 18. The protective tube 27 is thereby retained from the front end of the cannula hub 17 and compressed like an accordion. After that Handle 22 completely pushed onto the cannula hub 17 is, the handle is as described in Ring 19 locked and the blood can be drawn will. There is a possibility instead of double-ended multiple withdrawal cannula 21 a normal Cannula with a cone at the rear end on the Put on blood collection device. To this end the cap 16 is removed from the cannula cone 14 and put on the normal cannula.
- the front end of the inner tube 11 has one End wall 30, which is substantially flat and in which there is a central passage 31, which is aligned with channel 15.
- the separating body 33 is located in the inner tube, which has a narrow annular piston surface 34, which is the volume of the inner tube like a Piston divided into two separate chambers. To the other places is the diameter of the separating body 33 smaller than that of the piston surface 34.
- the rear End of the separating body 33 is with a piston rod 35 connected, the cross-shaped ribs there is and a handle plate at the rear end 36 wears.
- the piston rod 35 protrudes from the open ends from the inner tube and the outer tube. If the separating body 33 in the front end position is located, that is, against the end wall 30, stands Handle plate 36 out of the outer tube. By Withdraw the piston rod 35 and through the sealing The suction of the piston surface 34 takes place of blood into the inner tube. After completion this aspiration becomes the piston rod 35 on one The predetermined breaking point 37 is broken off by the separating body 33.
- the separating body then forms the inner tube sealing plug.
- FIG. 3 shows, the edge of the end wall 30 of the Inner tube 11 designed as a bead-shaped locking profile 40, at the back end by a constriction 41 in the outer surface of the peripheral wall of the inner tube 11 is limited.
- This locking profile 40 acts with a counter profile 44 together on the inside of the outer tube 10 immediately adjacent to it End wall 13 is formed (Fig. 2).
- the counter profile 44 is an annular trough on the inside a reinforced area 42 provided the transition from the peripheral wall of the outer tube 10 to End wall 13 forms.
- the outside diameter of the locking profile 40 is slightly larger than the inside diameter of the counter profile 44.
- the locking profile 40 and the counter profile 44 form a biased Snap connection that snaps into place when the inner tube pressed forcefully into the outer tube becomes.
- the interlocking Sealing profiles 40 and 44 Because of the elasticity and softness of the material of the inner tube 11 are the interlocking Sealing profiles 40 and 44. On the other hand, that holds rigid counter-profile 44, the inner tube 11 with a large Force firmly so that the locking connection when aspirating, d. H. when pulling back the piston rod and the separator, is not resolved.
- annular circumferential point elevation 43 is provided (Fig. 2) which closely surrounds the channel 15 and from the End wall 13 protrudes axially into the outer tube.
- the end wall 30 of the inner tube Bias on the elevation 43 (Fig. 4). While the centrifugation digs the elevation 43 in the End wall 30 a. This will make the transition from that Channel 15 sealed to the passage 31 and it is prevented that liquid get into the annular gap 12 can.
- annular elevation 45 preferably triangular Cross section on the outside of the end wall 30 of the inner tube 11 is provided. This survey 45 is during the centrifugation on the end wall 13 of the The outer tube is pressed wide and thus ensures a seal around the passage 31.
- Fig. 6 shows the rear end of the inner tube 11.
- the inner tube indicates one to the outside protruding thickened area for rubbing support on the outer tube 10.
- a braking groove 46 is formed, the the piston surface 34 of the separating body 33 in the rear Detects end position. In this position the piston rod 35 can be broken off by the separating body 33 will.
- the effect of the brake groove 46 is there to avoid pulling out the separator 33. This effect is caused by the thickened area 47 reinforced, which is supported on the outer tube 10 and expanding the inner tube at the back End prevented. This will result in accidental pulling out of the rigid separating body 33 from the inner tube prevented.
- the brake groove 46 is designed that the separating body 33 in the rear end position against the negative pressure formed in the inner tube holds on.
- the blood can also be taken vacuum extraction technology, in which a negative pressure is generated in the inner tube 11, immediately before the blood is drawn.
- Another job of the thickened area 47 lies in the rear Sealing of the annular gap 12.
- the sealing ring 48 prevents that the serum / plasma supernatant obtained by centrifugation during further sample processing in reaches the annular gap 12.
- the separating body 33 shown in FIGS. 6-8 is an asymmetrical tilting body according to EP 0 056 609 B1 trained so that it correspondingly during centrifugation the inclination of the centrifuge cup different Inclinations in relation to the tube axis can take.
- In front of the ring bulge Piston surface 34 are two pointed at their ends tapered legs 50a, 50b, which are separated by a gap 51 are separated from each other.
- the gap 51 is only on one side and open towards the front and at the back closed by a peripheral wall 52.
- the Legs 50a and 50b have at least to the longitudinal axis a bevel 53, the inclined positions of the separating body in the expanded inner tube.
- the Separating body 33 consists of a material whose density between that of those to be separated Blood phases.
- the outer tube 10 can be put on by a cap 55 (Fig. 9) are closed.
- the cap only sits in the outer tube and seals the rear end of the outer tube. Since this the rear end protrudes beyond the inner tube, comes the cap with the inner tube not in touch.
- the cap 55 forms an additional cover. The Centrifuge with the cap on certain centrifuge designs to avoid the Aerosol effect makes sense.
- a centrifuge cup 56 is shown, the with a radial distance from the axis of rotation of a centrifuge rotor is arranged hanging.
- the rotor rotates the centrifuge beaker with its lower end pivoted up in the direction of arrow 57 so that it finally takes an approximately horizontal position.
- On the bottom of the centrifuge cup 56 is a centrifuge insert 58 arranged, the rigid plastic consists.
- the centrifuge insert 58 has a peripheral wall 59 with which it is centered in the centrifuge cup 56.
- An annular collar 60 protrudes from the peripheral wall 59 surrounds the ring 19 of the outer tube 10 centering.
- the peripheral wall 59 encloses an annular centering wall 61, which receives the cannula hub 17 centering.
- the centering wall 61 has a bottom wall 62 connected, which is on the bottom 63 of the centrifuge cup 56 supports. From this bottom wall 62 stands a central pin 64 from which in the front end of the cannula attachment 17 penetrates and on the membrane 18th is supportive.
- the centrifuge insert 58 is seated Movable in the centrifuge cup and can be used if necessary (e.g. for cleaning).
- the outer tube 10 lies with a ring 19 surrounding it Ring shoulder 65 on the end face of the centering ring 60 on.
- the pin presses 64 into the rubber membrane 18.
- the rubber membrane 18 pressed against the pressure of the liquid column and seals the container so that no liquid emerge into the centrifuge cup 56 can.
- the closure cap 55 can be designed so that it can be pierced by a sample needle. This enables sampling in a closed system.
- the blood collection device may alternatively be that above described embodiment a vacuum included to suck up the blood.
- a vacuum included to suck up the blood In this case only the separating body 33 is present in the inner tube and the piston rod 35 is unnecessary.
